Jaguar XJ (X350). Manual — part 164

•

Brake pedal is low or feels spongy. This condition may be caused by no fluid in the brake
master cylinder, reservoir cap vent holes clogged or air in the hydraulic system.

•

Brake pedal effort is excessive. This may be caused by a bind or obstruction in the
pedal/linkage, a faulty non return valve, booster or insufficient booster vacuum.

•

Rear brakes lock up during light pedal force. This may be caused by damaged brake pads, a
partially applied parking brake, a damaged ABS sensor or bearing failure.

•

Brake pedal effort erratic. This condition could be caused by the brake booster or incorrectly
installed brake pads.

•

Brake warning indicator is on. This may be caused by low fluid level or float assembly
damaged.

Non Pressure Leaks

Any reduced fluid volume in the brake master cylinder reservoir condition may be caused by two

types of none pressure external leaks.

Type 1: An external leak may be occur at the brake master cylinder reservoir cap because of incorrect

positioning of gasket and cap. Reposition cap and gasket.

Type 2: An external leak may occur at the brake master reservoir mounting seals. Repair such a leak

by installing new seals and make sure that the brake master reservoir retaining bolt is correctly

installed.

Type 3: An external leak may occur in the manual transmission clutch operating system. For
